Guna
Guṇaगुण· GOO-nahquality, strand
The gunas are the three fundamental qualities of nature in yoga philosophy — sattva, rajas and tamas — that combine to shape everything, including the mind.
The Sanskrit guṇa literally means "thread," "strand," or "rope," and by extension "quality" or "attribute." In Sāṃkhya and yoga philosophy it names the three strands woven together in all of nature — much as strands twist into a single cord, the three guṇas combine to form everything you experience.
As your short definition notes, the three guṇas — sattva, rajas and tamas — are the fundamental qualities of prakṛti, primordial nature. Every object, food, mood and thought is a shifting blend of the three: sattva as harmony and clarity, rajas as activity and passion, tamas as inertia and heaviness. Their proportions constantly change.
The Bhagavad Gītā treats the guṇas at length, devoting its fourteenth chapter to them; verse 14.5 states that sattva, rajas and tamas, born of prakṛti, bind the embodied self. Sāṃkhya philosophy, on which yoga draws, develops the same threefold model of nature.
You meet the guṇas daily. A light, fresh meal and a calm mind lean sattvic; caffeine, ambition and restlessness are rajasic; oversleeping, heaviness and dullness are tamasic. Yoga does not aim to erase rajas and tamas — you need drive and rest — but to let sattva gradually predominate.
A common misreading treats sattva as "good" and the others as "bad." More accurately, all three are natural and necessary; imbalance, not any single guṇa, causes trouble. The deeper aim of yoga is not merely a sattvic mind but freedom from being bound by any of the guṇas at all.
Frequently asked questions
- Are the three gunas the same as the doshas?
- No. The guṇas — sattva, rajas and tamas — are qualities of mind and nature in yoga and Sāṃkhya philosophy. The doshas (vata, pitta and kapha) are bio-energies in Ayurveda that govern the body. They come from related worldviews but describe different things.
- Can you actually increase sattva?
- To a degree, yes. Fresh food, regular sleep, honest speech, time in nature, meditation and steady practice all tend to raise sattva. The guṇas shift by the hour, so it is less about reaching a fixed state than gently favouring clarity over time.
